s claims. (ci. 'z2-4a) This invention .relates to an improved fireproof wall construction and more particularly to thesteel work therein and method of constructing the same and applying cement and plaster.

'Ihe primary object of the invention is to provide a strong but inexpensive iire-proof construction in which the wall is made up of a plurality of integrally formed slabs which are resulating material designed so that the outer wall may be flnished/ very quickly and provide protection for inside worlnnen installing electrical work, plumbing work, or the like, and permitting the inner wall to be put in at any convenient later time.

I'he invention is illustratedin .a preferred em- `bodimentA in the accompanying drawings, in

Fig. 1 is a broken elevational view ofa wall embodying the invention', with part oi' the constructionvbroken away; Fig. 2, a. broken plan sectional view taken as indicatedfat line 2 of Fig. 3; Fig. 3, a broken vertical sectional view taken as indicated at line 3 of Fig. 2v; Fig. 4, an enlarged perspective view of one of the separators used for spacing and securing the structural members together; and Fig. 5,V a broken elevational view showing how Athe structural column members may be secured to fa foundation. i

In the embodiment illustrated, A designates a foundation upon which an outer wall B rests; and C an inner wall which is secured to, and supportedv by, the outer wall B.

. The foundation A may be of any suitable conl and may have horizontal metallic structural base members I0 secured thereto by nails II, or other suitable means. Preferably the base members I 0 are raised slightly above the foundations by means of spacers I2, or are bent to provide space for the reception of wires I3 or clamps which hold metal lath I4 on the outer wall.

In some cases the -outer wall B may be provided 'with large frame members I5 of any suitable cross section such as angle iron or the like and these members vmay be secured to the foundation and reinforce the construction. However, the wall consists primarily of pairs of upwardly extending metallicstructln'al members I6 which are secured vtogether in spaced relation by means of separators I1 to form double column members which are secured to the horizontal base members I0 as indicated atrv IB' in Fig. 5. Transverse structural ,members I!v are 6 interleaved between the members I6 andare flxedly secured thereto in vertical spaced relation. Additional single column structural members 20 are disposed at spaced intervals between the double column members I6 and are attached l0 to the nuter'base member I0 and to the trans` verse members I 9. The metallic structural members may be of any suitable cross section although channel members, as shown in the drawings, are preferable. 'I'he vertical columns I6 and 2li are arranged so that the finished wall will be divided up into integrally formed small slabs whose load is transmitted by vthe transverse members I9' to the column members I6 and 20. A satisfactory f arrangement is to place the vertical columns 20 about sixteen inches apart for ordinary construction. The transverse members I9 may be spaced three or four feet apart. 'Y

It will be understood that after the structural members have been erected the metal lath I4 25 may be attached to the outer side thereof and separator members 2lv attached to the inner side to grip the inner wall C. T he outer wall is now ready forfthe iirst coat of cement 22 which maybe applied on the outside with a trowel in 30 the usual manner. After allowing about two hours `for the outer coat to set an inner coat 23 lmay be applied from the insideof the wall lin any desired manner such as spraying, by hand,

vbut this step is not essential. An additional outer coat 2l and iinish coat 25., which may be of color, can be put on at this time, -or.later, to suit the convenience of the builder. In either case it will be understood that the inside work- 50 men' will have weather protection. Ordinarily panels which are framed by the inwardly extend- 60 members and vertical column members. The panels, although light, have great strength and rigidity due to the arrangement of the ribs.

As shown in Fig. 1 a window frame 26 may be' provided in the metal lattice work ofthe wall and is provided with outwardly extending arms 21 which are secured tothe vertical column members and are rmly embedded in the cement of the outer wall. 'I'he arms may be attached inany manner such as by bolts 28. Door frames and other parts may be installed in like manner before the cement is applied.

The inner wall C is formed by securing the structural members 29 tothe separators 2i and to these structural members may be attached more metal lath i4 to receive plaster 30. As stated above, the intervening space will receive plumbing work, electrical work, or the like, and the remaining spaces may be lled with any suitable insulating material 3| such as rock wool, asbestos ber, or the like. In s'ome cases it may be desirable to. provide ties on the inside of the metal lath nNon the innerwall to hold the insulating material from packing down. A,

Thus it will be seen that a wall is obtained wherein the only direct connection between the inner wall and the outer wall is by separators 2i whose cross sectional areas are so small as to be practically negligible as heat conductors. Accordingly, the wall will have excellent heat insulating properties. vThe double column construction oi small structural elements provides great rigidity Without excessive use of material and is adapted to other concrete slab constructions other than walls, such Ias floors and the like.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed asibroadly as permissible, in view of the prior art.
